Why are you always eating?

I was having an orange today at my desk and one of my Co-worker came and asked why are you always eating? I replied "I'm trying to be healthy by eating frequently" He replied " That shows in your weight" and went away.

Yes I'm overweight . I'm trying to eat healthy and working out regularly. I''m snacking on fruits and i bring fruits to office everyday. These days lot of people are asking this question to me. How to deal with this? Any ideas?

no prob.  :)
